(54) Bead set, production process of the bead set, and method of using the bead set


(57) A bead set is composed of plural subsets of beads. The beads in each subset are each provided with a surface permitting immobilization thereon of a substance that takes part in a predetermined corresponding reaction or interaction. The individual beads in the beat set are provided with different physical elements, respectively, such that the individual beads in the bead can be distinguished into the plural subsets through an analysis of captured images of the individual beads in the bead set by a computer.
